Heat pumps in London homes
Terraces, flats, lofts and extensions
London homes bring their own questions, like where the outdoor unit can go, how it will sound to you and your neighbours, and where a hot water cylinder could fit. We address them through careful assessment, transparent explanations and detailed heating system design, including an assessment of your existing radiators or underfloor heating.
Rather than relying on assumptions, we calculate your home's heating requirement with a heat loss calculation. Why sizing matters.
Planning. In England, most air source heat pumps on houses can go in without planning permission under permitted development rules, which were relaxed in May 2025, as long as they meet conditions on size, position and noise. Listed buildings, flats and homes in conservation areas can have extra rules, so check with your council before you commit.
North London
Heat pumps and heating in North London
We cover North London for heat pumps, boilers, central heating, underfloor heating and servicing.
Our Bushey case study is just over the border in Hertfordshire: a 12 kW Vaillant aroTHERM plus, where our approach enabled a maximum weather compensated flow temperature of 40°C where the original design allowed 45°C. Its SCOP is over 4.0 so far, with updates to follow.

Boilers and servicing
Boilers, and keeping things running
Not every home is ready for a heat pump, and not every budget is. We fit new and replacement gas boilers as a Gas Safe registered engineer and accredited installer for Vaillant, Viessmann, Intergas and ATAG, and we can give you honest, informed advice on both options.
Recent London jobs include the renovation of a large property in Waterloo, a full plumbing and heating project; a full heating and plumbing installation in Richmond upon Thames; and a penthouse renovation in North London. See the projects
We also service gas boilers and heat pumps across London.

NuRenewables Heating Ltd have been outstanding from the very start. Every single time I've called them out, they've gone above and beyond what I'd expect — always punctual, polite, and incredibly helpful. The quality of their workmanship is excellent — everything is done thoroughly and to a very high standard.
What really sets them apart is their knowledge and expertise. They've always taken the time to explain things clearly, give honest, sensible advice, and never try to push unnecessary work on me. I really trust their recommendations.
On top of that, the pricing is exceptional value for money — fair, transparent, and worth every penny. And what truly impresses me most is the ongoing support and service after the job is finished. They don't just disappear — they're there whenever I need them, ready to help with any questions or follow-up.
If you're looking for a reliable, knowledgeable, and trustworthy heating company, look no further. I'm so glad I found them — highly recommended! Thank you for such wonderful service every time.
Amazing service, so responsive, problem sorted and sensibly priced work.
Kirk and his team have been excellent in their assessment of our heating and plumbing issues. Professional friendly accessible and caring. Also responsive to any queries many months after the job. Our boiler was replaced and multiple plumbing issues. If you want first class service please contact Kirk!
Questions
London questions, answered
Do you cover my part of London?
We cover London, including North London. Send us your postcode and we'll let you know.
Do I need planning permission for a heat pump in London?
Usually not for a house. In England, most air source heat pumps can go in under permitted development rules, as long as they meet conditions on size, position and noise. Listed buildings, flats and homes in conservation areas can have extra rules, so check with your council first.
Can you fit a heat pump in a terraced house?
It depends on whether there's a suitable place for the outdoor unit and whether the radiators can be sized to suit. That's part of the property assessment and survey. We explain the available options and recommend solutions based on your home's requirements, rather than simply selling equipment.
Do you service boilers and heat pumps in London?
Yes. See boiler servicing and heat pump servicing.
